The invention is designed to facilitate building houses of arti'cialstone by molding the' Wall in sit/a or as it is being built; and theinvention consists in the novel construction and. combinations ofdevices, as hereinafter set` forth.

The material to be used is such as is used ordinarily for artificialstone, and .the wall may be either built up of the material in simpleform, or it may be built of artificial-stone veneer or facing with acoarser filling of concrete, the .entire wall being worked up from baseto top'or in such sections as may be found convenient in theconstruction.

In the accompanying drawings, illustrating the invention, 5 represents aback piece for molding the inner side of the wall. It may extendlengthwisev sufciently for molding a part of the wall corresponding toone stone or to several stones, and it may be grooved, as at 21, to forma base-molding near the floor serai 110.175,37?. or@ model.)

or, aslat- 22,', to'form a molding near the ceilingi- The back piece isprovided with projections or lugs 23, extending upward from its outersurface to engage the nextback piece above it. A perforation 24 ismade'about the middle of the back piece for thepassage of the rear endof a bolt-rod 25, which also. ex-

tends through a similar hole in the front piece This bolt- --13 and isprovided with a nut e. rod serves to hold the front and back piecestogether temporarily'while this part of the wall is being molded. To thefront piece, on the inside and around the marginal portion thereof, isattached an open metal frame 6 for holding the die-plate 26, which formsthe face of thestone.- The frame 6 is made with a rabbeted verticalfedgeand horizontal edge,

-as indicated at c, and with a corresponding projected vertical 'edge'and horizontal edge,

as indicated at b, whereby it is adapted to fit in line with and engageother frames of similar character above, below, or o n` either or bothsides thereof. The length of this frame and ofthe front piece or covermay be suflicient to form-the appearance of one stone or several'stones, as may be advisable. The inner edge of the frame 6 is designed'to project inward beyond the general plane of the` dieplate 2 6 in orderto provide apurchase in the wall for holding the part in 'position and`tomold the depressions serving to represent the mortar seamsoutlining-:the representation of ,the stone. The die-plate may havethumbscrews f, which pass through perforations of the front piece andare secured by engagement with the part back of said front piece.

Between the back-piece 5 and the frame 6 are placed the spreader's S,which are made of different widths in accordance with the thick- -nessesof wall in common use, and when these spreaders are in position and thenut on the bolt-rodis screwed up the mold is ready for use, in so far'asits general form is concerned, for molding artificial-stone compositionsolid or without interior modification.

Various die-plates having different designs may be employed inconnection with the frames'and front pieces, such die-platesbeinginterchangeable With each other or'with a plane-surface die-plate. Thesedesigns may be bevel-edged, paneled, or otherwise figured in relief ordepression, as may be desired.

Then it is desired to use liner material for the exterior surface orsurfaces ot' the wall and coarser concrete for lilling, thedivisionplates l0 are employed, these division-plates havingI offsets orflanges c to keep them the proper distance from the die-plate and backpiece and being provided with vertical slots d, open at their lower endsto pass freely by the bolt-rod of the mold. The flanges c are beveledoli at their lower ends, as at m, to allow the veneer composition toreach the ends of the mold. These division-plates and the spreaders areprovided with handhelds or catch-slots e, which serve to enable them tobe drawn upward out of the material of the wall as such material isbeing pressed or tamped solid. When the division-plates are in position,the liner composition isv placed between such plates and the surface dieor back piece, while the coarser filling is placed between the front andback division-plates when both are used or between the frontdivisionplate and the back piece when only the front division-plate isused. As the material is illed in it is pounded or tamped down by meansof suitable stamping-tools, the division-plates and spreaders beingraised from time to time during the operation until the structure ismade solid to the top. Molds for forming the corner portion of the wallare ot' similar structure, having a die-plate 4 at one end instead of atemporary spreader. Such corner-die plate is designed to correspond instyle with the plates used on the face of the wall, and it may besecured by means of thumb-screws to the back piece 5 and to the frame 6.

Sometimes it is desired to provide ahollow wall construction,which willrequire less material and will dry more rapidly. For this purpose thecavity-former /L may be employed. This consists of a series of verticalblocks attached to a longitudinal connecting-bar Z, which serves as ahandle to place and withdrawthe device. For windows and doors similarmolds are provided, with such modifications as are proper for the designaround the window-opening or door-opening. A bevel-end die-plate forsuch a mold is indicated at 7 and a round or swell die-plate at 35. i

In the process of making a wall a sufficient number of back pieces,frames, spreaders, dieplates, bolt-rods, and division-plates, if thewall is to be veneered with tine stuff, are provided to lay the cementrepresenting the lirst course. Then, it' starting at acorner, an endplate of proper design is attached to the end of a mold which is placedin position on the foundation, which has been previously leveled oli. Ifthe stone is to be all of one kind of material, the mold is now ready tolill; but if the stone is to be inished with a facing or facings ofliner stuii' the division-plates are put in position. The lirstmold isthen partly lilled with the material to be used, the coarse lillinginthemiddle portion and the line veneer composition between the die-plateand the division-plate and, if the wall is to be laced inside,betweenthedivision-plate and thebaek piece. The division-)lates are then raiseda little and the materials pounded down by means of swages, so that theliner and coarser materials come together solidly under thedivision-plates, which are then raised again and the pounding continued,and so on until the mold is lilled and the lilling and iaeingcompositions are pressed together, so that they will harden as onestone. dien the front cover-piece is used tor the face oi the stone inconjunction with a die-frame to lorm a bevel edge or a panel-margin, thenut oi the bolt-rod may be taken oiil and the bolt-rod partly removed.Then the cover-piece may be removed and the die-trame allowed to remainfor a while until the face portion is polished, the hole made by thebolt-rod being plugged. This operation is repeated to form that portionof the wall next the part which has been formed, and so on until thislayer ol wall is completed. The spreadcrs are taken out as the wallcourse is laid, so that each portion is pressed solidly in contact withthe next. The layer above this one is built in the same way, the lowerlayer being hardened snliiciently to allow the molds to be placedthereon, or the lower molds may remain in .wf/H and the molds of thenext layer placed thereon until two or more layers ot' the wall arebuilt. When the upper layer is linishcd, the lower set of molds may betaken olii' and used to form the next layer above. ln laying alternatecourses the molds may vary in position at the corner the distance olE ahalt-stone, il a half-lap is desired, the frames being adapted to slidealong and lit anywhere on top ol each other. Usually but two sets ofmold apparatus-that is to say, a sullieient number of sets for forming aheight ol wall equal to two courses of stone will be found sulicient tobuild a wall or' any height. ln the construction itis apparent that theback pieces are held in position in the hardening cement by means ot'the partly-withdrawn bolt-rods and that the metal front trames are heldin position by being set into the channels which are torepresent themortar seams. Die-plates which have deep designs may be filled with thefacing-cement before being set in place in the frame, and when theinside filling is pounded against it the whole becomes irmly knittogether. In this case the liront divisionplate may be dispensed with.Then a course of the artilicial stone is laid and is designed to beallowed to harden before the next layer is put on, the lower course maybe recessed with inward-inclined lianges or ribs to lorm a dovetailrecess, so that the next layer will 'IOO IIO

When pressed down be locked in to it atjitsV bottom. When both outsideand inside sur-V faces of the Wall are to be finished plain, thev frontpiece of the mold may be made like the; back piece.

The sills, sides, vand tops of openings for. Windows and doors'canl bebuilt up of thel artiicial-stone composition around the Window and doorframes by using properly-designed die-plates and molds adapted tolit-each other, as hereinbefore indicated for the vvalls. Such devicesare indicated in Fig. 9 of the drawings.

In making columns I employ ahinged frame 69 for molding the base. 70indicatesfan octagon .plinth-frame next the base, andl a bead-frame.tinuing the molding process to the upper end of `the column. These areeach designed to be hinged on one sideand connectedat the opposite sideby Ameansof lugs and a key. The removable cylinder 7 7 is employed forthe veneering. This veneering device may also have a fluted contour. Itis designed to be provided with handles for adjusting and lifting.

In building the main Wall each back piece may also be provided withinterior anges for penetrating the Wall as it is ybeing built to aid insupporting the back piece above it.

When a die is used which is stamped to mold an imitation of chippedstone or rubble-y face, such die may be used Without a cover,y as thesurface does not require nishing of.

In this-case the cover and die may be said to be in one piece.
